im running a b18b jrsc w/crv pulley right now on itr catback. i think 2.25" or 2.5" is a nice size if you plan on having 8lbs+ of boost.

Usually for forced induction cars people go with 2.5" exhausts.

3"

2.5 is to small.

jacksonR

2.5" is pretty good, i think 3" is too big.
3" is nice for turbo

exhaust size depends on the hp figure you run, sure you can slam a big pipe on your engine, ya it sounds good, but that doesn't mean you are getting the most from that size pipe, exhaust systems on supercharged and turbocharged engines are apples to oranges, remember superchargers do not run off the exhaust. Also, changing pipe sizes will alter the engine's tune.
